This product family provides up to 10A of output current or 33W of output power in an industry standard, compact, IC-like, molded package. It is highly integrated and does not require external components to provide the point-of-load function. A copper pad on the back of the module, in close contact with the internal heat dissipation components, provides excellent thermal performance. The assembly process of the modules is fully automated with no manual assembly involved. These converters possess outstanding electrical and thermal performance, as well as extremely high reliability under highly stressful operating conditions. IPM04S operate from a 3V~5.5V source and provide a programmable output voltage of 0.8V~3.3V. The IPM product family is available in both a SMD or SIP package. IPM family is also available for input 8V~14V, please refer to IPM12S datasheet for details.

Current is measured at the input of the module. Figure 23: Input reflected-ripple current test setup To maintain low-noise and ripple at the input voltage, it is critical to use low ESR capacitors at the input to the module. Figure 26 shows the input ripple voltage (mVp-p) for various output models using 2x100 uF low ESR tantalum capacitors (KEMET P/N:T491D107M, 100uF/16V or equivalent) or 2x22 uF very low ESR ceramic capacitors (TDK P/N:C3225X7S1C226MT, 22uF/16V or equivalent).

When the module is not soldered (via socket), place Kelvin connections at module terminals to avoid measurement errors due to contact resistance. The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the module. An input capacitance must be placed close to the modules input pins to filter ripple current and ensure module stability in the presence of inductive traces that supply the input voltage to the module. η =( Vo × Io ) × 100 % Vi × Ii 7 DS_IPM04S0A010_12182006 DESIGN CONSIDERATIONS Safety Considerations For safety-agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards. For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a maximum 10A time-delay fuse in the ungrounded lead. FEATURES DESCRIPTIONS Over-Current Protection To provide protection in an output over load fault condition, the unit is equipped with internal over-current protection. Whe
